This patch is an adaptation of what I use in my .emacs.el, originally
the patch was correct, I have then deleted it (because the patch was
refused) and then created it again on your request, forgetting to merge
one line; Use let* instead of let.

Don't expect me to send another patch for such trivial change and more
generally to collaborate anymore on any emacs bugs.
